塗装部に加熱、冷却の熱ストレスが加わつた場合
は早期に剥離を起すことは明白である。 Conventionally, the method of painting a cylindrical body is to apply the paint by air spraying, dipping, pouring, etc., and then drying at room temperature, heating drying, and baking, as shown in Figs. Since the parts are arranged vertically or the cylindrical shaft 3 is arranged horizontally and in a stationary state, the paint 5 flows downward, creating dripping parts 6 of the parts with uneven coating. This phenomenon is particularly noticeable when the paint 5 is dried at room temperature immediately after being applied. This drying at room temperature means that if the paint is rapidly heated and dried after it has been applied, the surface of the paint 5 will dry quickly, and the solvent contained inside the paint 5 will thermally expand and even if it tries to come out. impeded by the skin of the paint 5, and as a result,
This work is performed to prevent blistering, and the paint 5 is dried at room temperature to such an extent that it does not easily adhere to the painted surface even if touched with bare hands. In this step, when the cylindrical body 4 is arranged in the above-described state, a thick part of the coating film, that is, a dripping part 6 is formed. Further, although the appropriate thickness of the coating film is 10 to 40 microns, the sagging portion 6 becomes more than 100 microns. Therefore, when the solvent of the paint 5 is scattered during drying at room temperature, the solvent in the dripping portion 6 is not easily scattered.
Considering that the solvent of paint 5 in other parts is sufficiently scattered,
When heating and drying is performed, the dripping portion 6 becomes a bulge in the paint 5 and becomes easy to peel off. Further, even if drying at room temperature is sufficiently performed and the solvent in the dripping portion 6 is sufficiently scattered, the dripping portion 6 may peel off due to the difference in thermal expansion of the paint 5 due to heating. Further, it is clear that even if there is no abnormality during coating drying and baking, if thermal stress due to heating and cooling is applied to the coated portion of the cylindrical body 4, peeling will occur at an early stage.

結果を得る。 In the coating method of this embodiment, the inner surface of the cylindrical body 4 is cleaned with an organic solvent (toluene, 1.1.1 trichloroethane, etc.) through the steps of brushing cleaning, vapor cleaning, and drying, and the paint is silicone resin varnish.
39wt%, inorganic heat-resistant pigments and extender pigments 55wt%,
It consists of 5wt% aromatic hydrocarbon solvent and 1wt% additive. When applying paint 5, dilute the aromatic hydrocarbon solvent to 30% and stir thoroughly until the viscosity is 100 seconds (Fordcup#4at20℃). Hold 3 vertically and pour from above. After that, the cylindrical shaft 3 of the cylindrical body 4 is placed in a horizontal state, and the cylindrical shaft 3 is set as the center of rotation.
The coated surface was dried at room temperature for about 10 minutes while rotating at a circumferential speed of 120 mm/min. Thereafter, it was heated and dried at 180°C for 20 minutes, and baked at 400°C for 1 hour. The arrangement of the cylindrical body 4 in this case is such that the cylindrical shaft 3 is horizontal and stationary. The rotation direction during room temperature drying may be either left or right, but better results are obtained if the rotation is always in a constant direction.

ができる効果がある。 According to the present invention, when the cylindrical shaft of the cylindrical body is placed in a horizontal state and the paint is dried while being rotated, the paint gradually flows in the direction of rotation, the scattering of the solvent is made uniform, and the paint film is further formed. It can be formed uniformly, and has the effect of being able to perform coating without peeling or blistering.
